BOTTLE CLOSUJRE OR CAP.

Application filed August 15, 1921. Serial No. 492,356.

To all whom it may concern:

Be it known that 1, ROBERT MURCHIE, a citizen of the United States,residing at Detroit, in the county of \Vayne and State of Michigan, haveinvented certain new and useful Improvements in Bottle Closures 0r Caps,of which the following is a'specification.

My invention relates to bottle closures 01' caps, and pertainsparticularly to caps co nstructed of paper or other similar material asused principally on milk bottles.

An object is .to provide a removable cap for a bottle so constructedthat the cap may be opened to discharge the. bottle contentswithoutentirely removing the cap from the bottle, but likewise permitting easyremoval of. the entire cap if desired.

A further object is to provide a simple, inexpensive form of bottle cap,comprising a lower perforate layer adapted to be removably fitted withinthe mouth of a bottle and an upper imperforate layer hinged theretoadapted to likewise fold within the bottle mouth but so constructed thatit may be upraised uncovering the aperture through the lower layer ofthe bottle cap.

A further ob 'ect is to provide a-bottle cap of form described aboveprovided witha hinged folding section adapted to unfold forming adischarge spout for the contents of the bottle as they pass through theperforation in the lower layer of'the cap.

.These and other objects together with details of construction will morefully appear from the following description, appended claims andaccompanying drawlng, in

which: i Fig. 1 is a perspective view -showing'the upper portion-of abottle with my improved cap in place therein.

Fig. 2 is a plan of the upper surface of the 1 ,cap.

.Fig. 3 is a plan of the upper surface of the cap, the closure layerbeing upraised.

Fig. 4 iskan elevation of the. intermediate folding section of the cap.Fig. 5- is a plan of the lower surface of the cap,. I C

In the drawings, let 1 indicate abottle, the upperportion ofwhichis-shown in Fig. 1, withinthe mouth of-which' the cap is fitted. ,Asuitable material for'the construction of-the cap is paper, as usedextensively for milk bottle caps today. -The cap comprisesa lower,-apertured layer 6. Layer b is pro-v vided with a large centralperforation c slightly elongated so the fluid will flow easily therethruover the provided spout. The lower apertured layer is adapted to fit snuly within the mouth of the bottle.

Iiinged at one side, to the upper surface of the apertured layer is animperforate layer F. This imperforate' layer maybe glued, riveted, orotherwise secured to the apertured layer, scored along the line 6 asshown in Figs. v1, 2 and 3, so as to be upraised uncovering theperforation c. This imperforate layer is adapted to fold down over theperforated layer within the mouth of the bottle, fitting closely within:the bottle mouth so as to be retained in position therein.

There is provided an intermediate folding section D. The middle section9 which is se-' cured to the imperforate layer, and the free ends h, kand h are secured to the perforated layer near the margin of theaperture therethru. This may preferably be accomplished by turning theseends within the perforated layer. The side portions 2' and z' of thisintermediate section are scored along the dotted lines in Fig. 4, so asto unfold as shown in Figs. 1 and 3, or to fold down' between the upperand lower layers of the cap, when the upper layer is closed down withinthe mouth of the bottle.

This folding section forms a trough-leading from the perforation overthe imperfoe rate layer and serves as a spout through which the liquidcontents of the bottle may be discharged. The folding section iscontinued to form a tab it by means of which the imperforat layer may beraised so as to uncover the amerture through the lower layer f the cap.

Having thus described my invention, what I claim is:

1. In combination with a bottle, a cap adapt d to be received within themouth thereof comprising an apertured layer adapted to fit'snugly insaid mouth, animper orate layer hinged to said apertured layer andadapted to fold thereover, within said mouth, a folding wall sectionpositioned intermediate said layers so as to fold'therein against whenthe imper-forate layer is closed down over the apertured la er andadapted 5 the bottle, an imperforate complementary layer hinged to the'apertured layer on one side adapted to fold thereagainst within themouth of the bottle, an intermediate folding section secured to saidimperforate 110 layer and to said aperture layer near the margin of theperforation therethru in such a manner as to fold therebetween when theiinperforate layer is closed down against said perforated layer and tounfold so as to form restraining walls of a trough leading from saidaperture over the adjacent surface of said imperforate layer when saidiinperforate layer is upraised.
